Why Is My Carbon Monoxide Detector Beeping?

If you’ve suddenly found your carbon monoxide detector beeping, it’s not something you want to ignore. At Summers Comfort Heating & Air here in Denham Springs, LA, we’ve had many homeowners call in a panic, unsure of what to do next. Understandably, that beeping can be alarming—and for good reason. It’s your home’s way of telling you that something might be wrong, and your safety could be at risk.

What Does a Carbon Monoxide Detector Beeping Mean?

When you hear your carbon monoxide detector beeping, there are several things it might be trying to tell you. Some detectors beep to signal the presence of carbon monoxide. Others beep because the battery is low or the unit itself is failing. So, how do you know the difference?

1. Carbon Monoxide Detector Beeping With a Display Showing Numbers

This usually indicates actual carbon monoxide in the air. Stop what you’re doing, get outside, and call 911. Then, call a licensed HVAC company like Summers Comfort Heating & Air to inspect your system.

2. Carbon Monoxide Detector Beeping Every 30 to 60 Seconds

If it’s a single chirp every 30 to 60 seconds, chances are it’s a low battery. Even so, swap out the battery right away. If the beeping continues, replace the entire unit.

3. End-of-Life Beeps

Most detectors are designed to beep when they’re reaching the end of their life span. Typically, this happens after 5 to 7 years. Check the label for the expiration date.

What to Do If Your Carbon Monoxide Detector Is Beeping

First and foremost, take every beep seriously. You can’t see or smell carbon monoxide, so you need to trust your detector.

  • Step 1: Evacuate if you suspect CO exposure.
  • Step 2: Call 911 from outside the home.
  • Step 3: Do not re-enter until emergency responders say it’s safe.
  • Step 4: Contact us at Summers Comfort Heating & Air to test your furnace or any gas-burning appliances.

How to Prevent Carbon Monoxide Leaks in the First Place

At Summers Comfort Heating & Air, we always stress that prevention is key. Thankfully, there are a few simple steps that can help you avoid that dreaded CO detector beeping sound.

Schedule Regular HVAC Maintenance

We recommend scheduling furnace inspections every fall. This allows us to catch cracked heat exchangers or faulty burners early.

Install Detectors in the Right Places

Place detectors on every floor, especially near bedrooms. Avoid installing them near vents or windows where fresh air could affect readings.

Replace Units as Needed

If your detector is over 7 years old, it’s time for a replacement—even if it hasn’t beeped yet. Better safe than sorry.

Can Your HVAC System Cause a Carbon Monoxide Leak?

Absolutely. In fact, we’ve found this to be one of the most common sources. Furnaces, boilers, and water heaters can all emit CO if they aren’t vented properly. If your carbon monoxide detector is beeping, we’ll inspect your system thoroughly to identify the issue.
